I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hoping this problem will be noticed by more people, the original post on this issue came from:https://forums.lenovo.com/t5/Linux-Discussion/T470-Linux-Power-Bridge-wrong-discharge-order/td-p/365...https://www.reddit.com/r/thinkpad/comments/63odjr/t470_battery_order_question_internal_discharges/ Brief description: same problem with OS including Win 10, Ubuntu 16.04, Gentoo etc. The internal battery always gets discharged first regardless its remaining power, which is generally harmless but seems not so good for the internal battery life. With my own T470 machine, updated with the latest 1.29 BIOS, this problem remains. According to searching results online, this little bug came with early versions of X's and T' including T460. PS: this issue had been successfully fixed with T460 via BIOS update 1.26, hoping it would be fixed with T470 sooner or later. Best regards.

Received a new T470 a couple of weeks ago, but having issues when running off battery (internal + 3 cell): 1. Power Bridge failure: sometimes if I unplug machine and run off batteries, then remove the external battery, the machine shuts off immediately rather than switching to the internal battery. This occurs 1/2 or 1/3 of the time. 2. When booting machine (if machine is unplugged, running on battery): sometimes it hangs indefinitely at Lenovo splash screen (i.e. with endlessly spinning icon). Only way out is to reset machine by punching reset button on the back. (Note: #2 occurs always after #1 occurs, and 1/2 or 1/3 of the time on a regular reboot). 3. However: boot hang never occurs if booting while machine is plugged in OR if external battery is removed (i.e. running with the internal battery only). Boot hang only occurs if booting off batteries and external battery is installed. I called Tech Support, they sent a new internal battery, but that makes no difference. They also said it might be a faulty system board, but I ran full Lenovo HW diagnostics and all tests passed successfully including mother board test. Also tried a complete factory reset (Windows 10 x64), loaded all latest updates & drivers incl. latet BIOS (1.30), which I reset to default values (F9). Problem still persists. Anybody else experiencing these issues?

Hi, I'm a T25 user. I've seen several posts about the new discharge behaviour on thinkpads (i.e. to discharge the battery with least wear first) however, like many other users I would like to discharge the external battery first, since I purchased the 72Whr battery for this purpose. In another post, it was suggested that this behavior might be fixed soon - any updates?

I have mostly used the Lenovo T series laptops.  At times I would have to unplug the power cord, pull the battery and push down on the power button to discharge power.  When lenoved came out wid models like the T480s that had a built in battery, they added a pin hole on the bottom that would simulate pulling the battery.  I can not locate any pinholes on the Lenovo L580.  Is there a way to discharge the power or simulate pulling that battery on this model?

I forgot where I read this from, but while I was reading up on how to assemble/upgrade a computer, I was told that when I was changing any components, I should power the unit down, flip the power supply switch to "off," then hold the computer power button for 30 seconds or so. The logic behind it was that it would discharge the capacitor or get rid of any trace amounts of electricity on the motherboard - is that true or a waste of 30 seconds??

Dear Experts,

Just wanted to quickly ask you that today, I took my desktop PC to a computer repair shop nearby and upon investigating my Asrock 945G-DVI motherboard thoroughly by the technician, he found that the motherboard is not leaving its discharge and that is the reason why after running my system for sometime, it gets shutdown automatically and the next time when trying to Power On, it just refuses to start.

However, if the system is left idle again for few mins, then it will Power ON but after sometime of running it will again face the same problem. So, he has told me to leave the system back with him and will call me back by evening to inform if motherboard can be repaired or he might need to forward it further to an expert to check the ICs and capacitors and see if this Asrock 945G (Intel Chipset) motherboard is repairable or not?

So before he calls me up, I would like to understand from experts out here as for what exactly is happening with my motherboard and are their any chances for the repairs of such issues to be successful?

One more thing: While the system was in my house, number of times the moment I Power On my PC, the LCB (Electrical system) switch used to trip down to cut off the power however, my computer would still remain Turned On but the lights and Fan in my bedroom would not start unless I lift that LCB switch back to ON....so tripping used to happen when trying to Power ON my PC.

I am looking to add a linux sat receiver to my current wireless network at home.

The sat receiver is a TM-9100 and it has the ability to change IP address to whatever you want/ need.

Basically I want to connect a gaming adaptor with a short ethernet cable to the TM-9100 so I can access the hard drive on the 9100 via my wireless network, there is one ethernet connection on the 9100.

Yesterday I aquired a Belkin Wireless G Gaming Adapter F5D7330UK, my router is a Linksys WAG300N with 3 laptops connected via wireless. The IP of the router is 192.168.1.1, the laptops are set at 192.168.1.51, 192.168.1.52 and 192.168.1.53 and are all running Windows XP home.

The Gaming adaptor has a 'out of the box IP' 192.168.2.225. I did change the IP of the gaming adaptor to 192.168.1.100 in the beginning, but it still would not work.

I tried channels 8, 10 and 11 at various times, I made sure all the wireless units were on the same channel each time.

I previously had my 9100 connected via a crossover cable direct to laptop with IP 192.168.1.51 and it connected to the internet no problem.

Now my dilema, I want to connect the gaming adaptor to my 9100 with a short cable, but, when I was trying it out last night I could only connect to either the router or the adaptor, but not both together.

I did try changing the ip address of the adaptor and 9100 but it didn't work, at least I couldn't get it to work.

The cursor is inactive here. I have not been able to change the UEFI to both UEFI and Legacy.

When the battery has charged 80%.It has stopped charging. But the discharging of the battery is not happening itself. I have to remove the ac power so that the laptop should start using battery instead of ac power. The battery should self discharge when it reaches 80% and start charging when it reaches 50%. which is not happening currently. Can any suggest any solution.

Here's how I got in this situation:

When I tried to access a website, the site attempted to download 'flash player'. Apparently; it tried to use 'active x' to perform this download, because I got the IE warning box about how the page wouldn't display properly, because I don't allow active x.

Well... my browser got stuck in a loop, and I couldn't even tell the site to close. The only way out of it, was to tell task manager to 'end task' on the attempted download. This caused my entire browser to shut down.

I tried to access the web again, but couldn't. It took several attempts, before I tried resetting my 'winipcfg', which worked.

Here is the problem though: Now... every time I boot up windows, my Norton AV loads before my ZoneAlarm. (They used to load in the opposite order). This is obviously either the problem itself, or at least a symptom of the problem, because I must now access my 'winipcfg' every single time I want to access the web!

Does anyone know why this happened, and what I can do to correct the problem?

Thanks!

no matter what i do my second drive (the one connected in sata 2 port) gets listed as disk 0 in windows 7 install program and later on in windows disk manager. i've even erased both drives (to unallocated) and repartitoned them from scratch hoping it had something to do with mbr but to no avail. ive tried switching ports on the drives, changing boot options in bios, but whatever i do second drive always lists as disk 0.

i've also tried installing windows with only the first drive connected, sure it works, but when i connect second harddrive later on it gets listed as disk 0 again and i have to change drive letters. (windows lists cdrom before second drive partitions)
this is the first time im experiencing this, i've never had this problem before using the same rig (albeit different harddrives).

Hello everybody,

I found that my XP (English version) is not able to put non-English characters in correct order, so that my Thai dictionary doesn't work properly.

Here are some details.

In Thai language, some vowels are on the left side of consonant, but when ordering those words with vowels on the left side, we don't consider the vowel is the first character, but XP does. I need to introduce 3 Thai characters in order to illustrate this problem more clearly.

ก is the first consonant in Thai language, ข is the second, ไ is a vowel which is on the left side of consonant, such as ไก and ไข. Now we put these 2 consonants and 2 words in proper order, it's supposed to be 1.ก 2.ไก 3.ข 4.ไข, but what XP does is 1.ไก 2.ไข 3.ก 4.ข

Is the any solution for this? Thanks in advance.

P.S. In the shop where I bought that dictionary, it works pretty well, but I didn't notice what system is was.

I bought a Lenovo T470 a couple years back with Win 10 for school and its been working great with absolutley no problems. Then last night i get home from work and go on to do school work and a message pops up saying battery not charging. It has the icon showing it recognizes that the charger is plugged in. Also the light on the lenovo logo is blinking 3 times red and repeating. When i unplug the charger it stops blinking. So I thought it was the charger, got out my multimeter and check it and it reads normal on both sides of the charger. Then I thought i needed a new battery but it wont even stay powered on with the power cord plugged in. So now it is dead and even with the charger plugged in will not turn on. Not even the power button light will illuminate. This laptop has been great to me and this happened out of the blue im hoping there is a way to fix this problem. And I also tried taking battery, unplugging it, hold power button for a reset. Nothing changed. Anybody have any ideas?

So I just recieved my T470 today, and I eagerly wanted to at least boot it up, but much to my surprise, when I plugged the cable in, I recieved no indication that it was plugged in or charging whatsoever. No green light anywhere, no heat, no nothing. I've tried various outlets, a different cord for the brick to the outlet itself, I checked out the battery on the inside and out to make sure it was all connected, etc. To say it's disatisfying is an understatement. Unless I can quickly get a cable before classes start (in one week), planning on a full refund because this is beyond disappointing to not be able to even using the dang thing.Edit: I have no proof it could be the power brick either, considering since there's no real way I could tell whether it's something with the motherboard or something like that.Edit 2: Tried another Thinkpad's power cord and brick, didn't charge or even show an indicator that it was charging (no green lights). Probably just gonna RMA it and hope for the best.

Hi,
I am developing a packet sniffer based on windows raw socket on windows 7. The program captures packet from IP layer. The issue i am facing here is that, Program captures all packets but some of them are captured in wrong order, for eg. for a tcp connection establishment phase, instead of getting packets in SYN , SYN-ACK, ACK order i get it as SYN, ACK, SYN-ACK. Instead of capturing ACK after SYN-ACK(from remote), pgm gets ACK before SYN-ACK packet. Same thing is happening some times during data transfer phase also. Program captures the ACK packet of a data packet before the actual data packet. If i run a wireshark in parallel, it displays properly. I am using Visual Studio 2005 as the IDE.

Hi, I read this blog post regarding Power Bridge.  I have the X250 with an internal 3-cell battery and an external 6-cell battery.  Windows 10 recognises both batteries.  The Lenovo Settings application recognises both batteries as well and indicates that both are in good condition.  When I take out the external battery, the laptop switches off.  The internal battery definitely works, because I tried the laptop on the internal battery only.  The thing is that one of the battery latches (not the one where you have to keep holding it to release the battery but the other one) broke, so the battery is not secured correctly.  It still works and mostly stays in but sometimes some movement might disloge the battery just slightly from the connector which results in the laptop switching off.  So if power bridge worked, this would't be a problem I think. Updated the bios to version 1.17 from 1.15. Thanks The X250 Specs:Core i7-5600U1920x1080 display8GB RAM256GB SSD

I have looked high and low and I cannot definitively find whether or not my late 2016 T460p does/does not or is/is not supposed to have an internal battery. I bought this laptop in late December 2016, and I am rather confident I read somewhere it is supposed to have it. However, everytime I remove the swappable battery, the laptop shuts off, and I have been receiving awful battery life. Anyway, with no external battery put in, the laptop thinks there is no battery; clearly my machine does not have an internal battery (or at least not one that works). I'm simply wondering if I am even supposed to have one and if so how I can get it fixed. Thanks!

I would buy the USB-C, thinking if or when I replace the laptop, the USB-C charger is more likely to work as a spare.  As far as wattage, the 45W will be lighter, but 65W may charge some devices faster and is more likely to be compatible with any replacement.  (I am not suggesting that you are going to replace the laptop soon, but things happen and situations change.)

Hi all,

I've been doing some research on my new build and started looking into power phases. After reading some articles, it seems like the less power phases you have, the more susceptible your motherboard is to failing, especially if you're overclocking. Plus you also have to worry about components on your motherboard overheating such as the mosfets. Is all of this something I should be worried about?

The motherboard I want to get has 8+2 power phases (Asrock P67 Extreme4 Gen3). So if I plan on overclocking, should I step up to a 12+2 or 16+2 motherboard or will I be safe at 8+2?

Thanks in advance
 

A:New Sandy Bridge build - power phases

The ASrock P67 Extreme4 Gen3 is an excellent board. It overclocks impressively. People have managed to hit the 5 GHz mark at around 1.45V with a good aftermarket HSF.

More power phases do not guarantee better performance. Generally, more phases should make for smoother voltage output, but it is only one of several factors in the design of the CPU voltage regulator.

My new X260 uses the internal battery before the external, hot-swappable battery. How can I change this? I'm on the newest BIOS (1.19?) and Ubuntu Xenial.

hello all i did try to read about this before asking here, but am confused by conflicting opinions on, whether it's detrimental to your notebook (particularly the battery) to either leave it plugged in to a power source all the time ...and whether you should ever let it completely drain off in order to recharge it? (cycle it?) ...the community here has helped me more times than i can count and, i trust in the knowledge and intentions of the people here, so... i wanted to ask here, where i know the folks won't steer me wrong...

and in a related concern, i was trying to find out... is it possible to/OKAY to, operate the computer with its battery cartridge removed if one does want to keep it plugged in to a wall for extended periods of time ...would that help prevent deterioration of the battery???

and separately, i know heat is no good for laptops ...i have a dell inspiron 1525 with a li-ion battery (i believe it's type gp952) that is about 1.5 years old ...so maybe the battery was on borrowed time anyway (?), but... it also has, without a choice, i'm afraid, overheated a few times this summer because i'm forced to stay in an attic, without any air conditioning or even a fan and, sometimes i feel like I'M going to croak, so i imagine it can't be good for the compu!

thank you all for spending your time here and lending your knowledge to the rest of us who need all the help we can get! ...god bless... *princi
 

A:notebook pcs : to fully discharge or NOT to fully discharge?! :)

Here is info on laptop batteries.
http://electronics.howstuffworks.com/lithium-ion-battery.htm
Being as the lithium ion battery only has about 5% self
discharge rate,it should be fine to leave it out for some time.
Try to charge it every 6 months or so.
Don't let it completely discharge.
Other types of batteries can have a memory effect and need
to be completely discharged periodically.
This is not the case with yours.

I've spent hours researching this annoying feature. If I leave the machine in sleep/hibernate state for more than about an hour and then open the lid, only the Lenovo logo is shown. CAD combo restarts but again only the logo is shown. I need to press the power button once, wait a few seconds then press the power button again. Then the laptop starts normally. The attached file shows my power settings. I appreciate any assistance. I have this problem whether I have my Wacom Pro S tablet attached or not. The laptop is brand new.

I was just wondering is the an order for a PC hardware to power up/on? If so were does one find that at. The last thing to power up is my GPU, is there a way to change it to make it the first thing to power up/on.

A:hardware power up order

Don't know whether this is what you're after, but I would have thought the basic startup procedure for any computer is pretty much set in stone:





"Although there are differences in how each computer actually starts, they all share these basic steps. This example is particularly directed towards Dos and Windows (except where noted).The computer performs a test on itself to make sure all components are available and ready. One important part of the first steps is that the registers (the place where data and instructors go in the CPU to be processed) are cleared of any old code. This is the start of the Power-On Self Test or POST test.
The CPU then gets a memory address from the ROM which where to find the ROM BIOS in order to continue the check.
The CPU now sends signals on its system bus, the main circuit on the mother board to which all components are attached.
The clock is checked by the CPU. All computer functions are regulated by this clock, which sends an impulse at a regular interval. It is very much similar to the beating of a bass drum to mark time in music.
POST tests the memory chips on the video adapter and loads information from the video adapter’s own BIOS into the system BIOS. Sometimes the BIOS codes from slower CMOS are also loaded into RAM. Newer PCs have additional equipment which also have their own BIOS on their own cards. These items, called plug and play also get loaded into the system BIOS.
The CPU now checks to see if a keyboard ... Read more

Hello, Thank you for your time, my issue started with a broken screen, I asked for a replacement through mail, when I installed the new screen it seemed to work fine. At a certain time of turning off the computer and starting it, the resolution is off by 86 pixels horizontal, the original resolution is 1366x768 (16:9), and now shows 1280x800 or multiples (w=1280,h=*). At first I thought it was an issue with drivers with Windows 10 the forums entries I found seem to indicate this, tried all of them. I also tried the custom screen resolution tool from Intel, it adds the resolution inside the tool, but it does not list the new resolution in the "graphics properties" section. With no luck at solving the problem I tried to boot a GNU/Linux Live version from a FlashDrive, with GNU/Linux showing the same resolution limitation. I've noticed that going to the BIOS is showing the same screen usage. After this, my old screen still works it just the crystal that got cracked, I reinstalled and noticed that has the same screen size problem, so is not the new screen it seems. This is the point till I've gotten, don't know much about UEFI maybe it saves screen resolution information at a place I can't reach, and is not adapting itself correctly imposing it screen scan to the OS that start to work after UEFI. The only thing that comes to mind. Your help is appreciated,Thank you.
